IMPALA-13076 Add pstack and jstack to Impala Redhat docker images
When the Impala docker images are deployed in production environments,
it can be hard to add debugging tools at runtime. Two of the most
useful diagnostic tools are jstack and pstack, which can be used to
print Java and native stack traces. Install these tools into Redhat
images which are the most commonly used in production.
To install pstack we install gdb
To install jstack we install a development jdk on top of the headless
jdk.
Extend the install_os_packages.sh script to add an argument to
--install-debug-tools to set the level of diagnostic tools to install.
The possible arguments are:
none - install no extra tools
basic - install pstack and jstack
full - install more debugging tools.
In a Centos 8.5 build, the size of a impalad_coord_exec image increased
from 1.74GB to 1.85GB, as reported by ‘docker image list’.
What other tools might be added?
- Installing perf is tricky as in a container perf requires an
installation specific to the underlying linux kernel image, which is
hard to predict at build time.
- Installing pprof is hard as installation seems to require compiling
from sources. Clearly there are many options and we cannot install
everything.
TESTING
Built release and debug docker images, and used jstack and pstack in a
running container to print Impala's stacks.
